Battery modules are charged and discharged to SOC Three different wirings tested: V1: all 4 modules in parallel, one pair of wires on the first, one pair of wires on the last V2: Modules 1+2 in parallel, modules 3+4 in parallel, two pairs of cables, DC+ on the first module, DC- on the second V3: all 4 modules in parallel, one pair of cables, DC+ on the first module, DC- on the last Residual capacity of the US2000C diverges in all of them. The behavior could be reproduced several times.
